Exhibit

{
  "model": "cohere.command-light",
  "compartmentId": "ocid1.compartment.oc1..aaaa...",
  "messages": [
    {"role": "user", "content": "Hello"}
  ],
  "parameters": {
    "temperature": 0.5,
    "maxTokens": 100
  }
}

Refer to the exhibit. A developer sends this JSON payload to the /chat endpoint. The response includes an error that 'maxTokens' must be an integer. What is the issue?

⚠ Common exam trap

Oracle often tests the difference between snake_case and camelCase parameter names in OCI services, and the trap here is that candidates familiar with OpenAI's API conventions might assume 'maxTokens' is correct, overlooking OCI's strict snake_case requirement.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The parameter should be 'max_tokens' instead of 'maxTokens'

The OCI Generative AI service expects the parameter name 'max_tokens' (snake_case) for specifying the maximum number of tokens in the response, not 'maxTokens' (camelCase). The error message indicates that the value is not being recognized as an integer because the JSON key itself is incorrect, causing the service to fail validation.
